I have 3 x Deco X10. 

Main unit is connected to my router/modem on which WiFi is disabled. The router/modem is then connected to a 16 port gigabit switch, feeding various other items at home. The remaining 2 Deco are also connected to that switch via cat 6 cable. 

However, in my "network map" in the Deco app, it shows the nodes as connected to the main unit wirelessly. How can I change this, as part of the reason for having the home "cabled" asking worth the resulting upheaval, was to allow the nodes to connect via cable. 

Anyone?
